@cundare2 The new KRELL that is represented by the Duo XD lineup is buttery smooth, very powerful, and decently detailed. It is the most relaxing gear I have owned or heard. Do some searches on A’gon on the Duo XD. Read the Stereophile review of the K-300i. those guys can give a better sonic description. Normally I do not like this type of sound, but I remember how much I enjoyed listening to the K-300i and then later the Duo 175XD amp.
For me the Luxman c900u | m90u | Luxman DAC | Harbeth was incredibly lush sounding. The Luxman 509x integrated amp on the same speakers and DAC was not as good nor as lush.
I used the AHB2 monos with the following speakers:
- Thiel CS3.7 (not a good match since speaker is hard to drive)
- KEF LS50 (great match)
- KEF LS50 Meta (great match)
- Audience 1+1 v3 (good but the room was bad)
- Yamaha NS5000 (best speaker I have owned. There is a touch of hardness on top)
I also demoed it with the Magico A3 speaker. It was awful with that speaker. Not enough power as a stereo amp (not mono).
